Subject: [RFC PATCH 2/3] fs: remove duplicate ifdefs

when a ifdef is used in the below manner, second one could be considered as
duplicate.

ifdef DEFINE_A
..code block...
ifdef DEFINE_A
..code block...
endif
..code block...
endif

There are few places in fs code where above pattern was seen.
No functional change is intended here. It only aims to improve code
readability.
